World's Most Powerful Collider Shuts Down for a Smashing Upgrade

Europe's CERN physics research center bids 'Farewell' to the Large Hadron Collider, but it's actually more like 'See You Later, Accelerator!' The new, improved High-Luminosity LHC is due to make its debut in 2030.

More Data and Machine Learning has Kicked SETI Into High Gear

For over sixty years, astronomers and astrophysicists have been engaged in the Search for Extraterrestrial Intelligence (SETI). This consists of listening to other star systems for signs of technological activity (or “technosignatures), such as radio transmissions. This first attempt was in 1960, known as Project Ozma, where famed SETI researcher Dr. Frank Drake (father of the Drake Equation) and his colleagues used the Robert C. Byrd Green Bank Telescope in West Virginia to conduct a radio survey of Tau Ceti and Epsilon Eridani. Since then, the vast majority of SETI surveys have similarly looked for narrowband radio signals since they are very good at propagating through interstellar space. However, the biggest challenge has always been how to filter out radio transmissions on Earth – aka. radio frequency interference (RFI). In a recent study, an international team led by the Dunlap Institute for Astronomy and Astrophysics (DIAA) applied a new deep-learning algorithm to data collecte...

SETI Researchers Double-Checked 1 Million Objects for Signs of Alien Signals

We can’t help ourselves but wonder about life elsewhere in the Universe. Any hint of a biosignature or even a faint, technosignature-like event wrests our attention away from our tumultuous daily affairs. In 1984, our wistful quest took concrete form as SETI, the Search for Extraterrestrial Intelligence . Unfortunately, or maybe fortunately, SETI has turned up nothing. Recently, scientists used a powerful new data system to re-examine data from one million cosmic objects and still came up empty-handed. Did they learn anything from this attempt? This effort used COSMIC , which stands for Commensal Open-Source Multimode Interferometer Cluster . It’s a signal-processing and algorithm system attached to the Karl G. Jansky Very Large Array (VLA) radio astronomy observatory. According to SETI, it’s designed to “search for signals throughout the Galaxy consistent with our understanding of artificial radio emissions. “ Modern astronomy generates vast volumes of data and al...

Review: Unistellar’s New Odyssey Pro Smart Telescope

Unistellar’s new Odyssey Pro telescope offers access to deep-sky astrophotography in a small portable package. Access to the night sky has never been simpler. The last half decade has seen a revolution in backyard astronomy, as ‘smartscopes’—telescopes controlled by smartphone applications—have come to the fore. These offer an easy entry into basic deep sky astrophotography even from bright urban skies, albeit at a higher price point versus traditional telescopes on the market. We’ve reviewed units from Vaonis and Unistellar before, as well as wrote commentary on the rise of the whole smartscope movement . Now, Unistellar has a new entry on the market in 2024: the Odyssey Pro . The Odyssey Pro is lightweight, at 14.3-pounds (65 kilograms) assembled plus carbon fiber tripod. The telescope sets up quickly, with the tube and base securing to the top ring of the tripod. Specifications for the Odyssey Pro The telescope at the heart of the system is an 85mm aperture reflector with an ...
